AIM:To investigate the effect of suramin concentration changes on trabeculectomy in rabbit, and to provide treatment strategies for glaucoma on the basis of experiment.
METHODS:Thirty-two albino rabbits were randomly divided into four groups, including standard control group, experimental group Ⅰ, experimental group II, and experimental group Ⅲ. Each eye was performed standard trabeculectomy. During surgery, standard control group was given a piece of cotton with 0. 3mg/mL mitomycin C ( MMC ) for 2min, and the other three groups were given a piece of cotton with 0. 3, 0. 4, and 0.5mg/mL suramin respectively for 2min. The filtering blebs and intraocular pressure ( IOP ) were observed at the 3, 7, 15, and 30d after surgery. Some conjunctiral specimen were observed with hitochemicall ( HE staining) and immunohistochemicall methods.
RESULTS:At postoperative 7, 15, and 30d, the changes of the IOP, functional filtering blebs, and the number of positive cell nuclear in experimental group II and experimental group Ⅲ were significantly different compared with those in standard control group and experimental group Ⅰ (all P<0. 05), and the differences between experimental group Ⅰ and standard control group were not significant (P>0. 05). The changes of the IOP and the number of positive cell nuclear in experimental group Ⅲ were significantly different compared with those in experimental group II (P<0. 05), whereas the differences in functional filtering blebs between experimental group Ⅲ and experimental groupII were not significant (P>0. 05). The status of filtering channel in experimental groupII and experimental group
Ⅲ were better than those in experimental group Ⅰ and standard control group.
CONCLUSION: The concentration of suramin has a significantly influence on its effect. When the concentration is 0. 3mg/mL, the antiproliferative effect of suramin is no more than that of MMC. The effect of 0. 4, 0.5mg/mL suramin is better than MMC. 0. 5mg/mL suramin has a better effect on controlling IOP and suppressing the growth of fibroblasts than 0. 4mg/mL suramin.

The growth and pigment production of 47 strains on casein medium were studied comparatively.T4 and Neurospora crassa AS 3.1602 were selected for their capacity of producing melanin on five different culture media. Melanin produced by T4 was investigated, and T4 was identified as Proteus mirabilis primarily.

The treatment plan of facial neuritis in Evidence-based Guidelines of Clinical Practice in Acupuncture and Moxibustion (2011 edition) is discussed, and case information of facial neuritis during the recent five years in department of acupuncture and moxibustion, PLA General Hospital, is retrospectively analyzed. In accordance with anatomy of the facial nerve to form the acupuncture prescription, the detailed diagnosis and treatment method for facial neuritis are introduced. The advantages of the diagnosis and treatment method for facial neuritis are summarized, hoping to establish a more comprehensive, standardized and unified treatment plan.

Objective To compare the adherent cells derived from human placenta,umbilical cord blood and bone marrow,and provide laboratory data for clinical application of mesenchymal stem cells.Methods Adherent cells were isolated from human placenta tissues by enzyme digestion,and mononuclear cells(MNC) were isolated from umbilical cord blood(UCB) by 60g/L HES and density gradient centrifugation and MNC were isolated from bone marrow(BM) by density gradient centrifugation,and then these cells were cultured in vitro.Their biological characteristics were studied and compared.Results The adherent cells cultured from human placenta and umbilical cord blood had disparate shape in vitro respectively.And they had some differences in growth and shape from those derived from bone marrow.The adherent cells derived from the three tissues all expressed CD106 and CD44 in immunohistochemistry staining.Conclusion The adherent cells derived from human placenta and umbilical cord blood have the basic features of mesenchymal stem cells.

Neoplastic stem cells (NSCs)are the source of tumor occurrence and development,and its special microenvironment is involved in tumor drug resistance,recurrence and metastasis by regulating NSCs or changing itself. Eradicating NSCs and interfering the special microenvironment may be the new therapeutic strategies for cancer.

Objective To evaluate the influence of partial parenteral nutrition on serum osmotic pressure,blood glucose,(biochemistry),bilirubin metabolism,immune function,growth and development of premature infants.Methods Seventy premature infants were randomly divided into control group and study group.On the base of enteral feeding,study group were offered parenteral nutrition, while the control group were supplied 10% glucose, fluid and electrolytes. Simultaneously, relevant indices were measured in 2 groups.Results 1.There were no significant difference in serum osmotic pressure,blood glucose and biochemistry before and after parenteral nutrition. 2.There were no significant difference in emerging and lasting time of jaundice between 2 groups.3.Serum IgG,IgA,IgM,C_3,CD4 and CD4/CD8 in study group were significantly higher than those in control group. 4.In study group the time of hospitalization and birth-weight regain were significantly shorter than those in control group.Conclusions There is no significant influence on serum osmotic pressure,blood glucose, biochemistry and bilirubin metabolism during partial parenteral nutrition. Parenteral nutrition may help gain weight, shorten the time of hospitalization, and improve immunological function of neonates.
